Re: hide / show oddities ?
There were some posts on this list about 4 months ago re: hide/show objects strangeness (http://runtime-revolution.278305.n4.nabble.com/hide-show-oddities-td4686263.html). Having struck this today on a project I’ve come to the conclusion that it’s something to do with the graphics caching that is being used when we have acceleratedRendering set to true. In our case, we had some scrolling groups with subgroups in which each contained buttons that may be shown or hidden at times. It appeared as though these weren’t being updated, however, if the overall containing group wasn’t visible. Once it was made visible however, scrolling the group would update all the child objects ok. However, that’s not good enough… So the solution for now, on entry to this card, is to turn acceleratedRendering off, which presumably disables the graphics caching, and all objects are now updated correctly. Yet to be seen is the effect this may have on other bits that perhaps need the better graphics performance… So if you’re also seeing strange behaviour with hide/show or setting the visible property, try turning off acceleratedRendering to see if that helps. (I’d already tried setting the layerMode and it didn’t seem to help).

Re: hide / show oddities ?
Thanks everyone for the suggestions, experiences, etc. Definitely not mismatched lock / unlock, since all the other parts of the screen are fully updated. I couldn't (naturally) recreate anything in a smaller sample, nor even reliably be sure to make it happen on demand. I finished up using a pattern rather like show grp abc set the vis of grp abc to true wait 0 millisecs with messages every time I want to show or hide things (and had seen a problem). No visible problems now - and no real idea how to try to track it down any further. I'll build an artificial deeply nested group structure in a stack, and randomly change the hide/show status of different groups within it, and test for visibility mismatches - and leave that running as a test. If that shows anything, I'll submit a bug report (and update this list for info - but I won't hold my breath :-) Thanks again -- Alex.

Re: hide / show oddities ?
Just to add that I got this working just now, in the strangest way. My code wanted to show a splash screen for three seconds, so I coded go to cd “splash” of stack “mySplashScreen” wait 3 seconds sometimes I put a ‘show’ in there too, but the splash screen didn’t show. I found that if I put wait 3 seconds with messages then the card does show up. Seems like snake oil to me. I hope I can create something simple that can be reported as a bug, but I haven’t got there yet. I should say that there shouldn’t be any messages, since this is pretty much the start of the program and no other actions have been launched (at least I don’t think so!).

I have a large project running under 6.6.x (all versions over the years) which uses hide/show all the time and it's always worked okay.

Interesting… When I reported my own stack anomalies with version 7, this sounds remarkably like what I was seeing, but I was showing and hiding stacks, primarily the main stack from which all other stacks were launching.

Re: hide / show oddities ?
Finding a recipe was my problem too. It hasn't happened for a while but I think it might have had something to do with nested groups. While we're talking about groups, I feel they're unnecessarily difficult to edit in LC. I find myself constantly clicking on the Select Grouped icon when I'm formatting groups and their controls. And trying to move a nested group to a different location is a pain - you should be able to do that without going into edit mode or being limited to using the arrow keys. I'd like to see something like this irrespective of the state of selectGroupedControls. If I click on a control within a group, it is selected. If I click within the rectangle of a group but outside the rectangle of any of its controls, the group is selected even if it's a nested group and I can then get into edit mode on it or drag it around the screen. That happens to suit the way I use groups but maybe it wouldn't work for all. I'd be happy if the above behavior was conditional on a modifier key in conjunction with mouse click.
