Re: opened socket in IDE prevents script changes
Look in the script editor breakpoints tab. If there are any there delete them. Just spitballing.

Re: opened socket in IDE prevents script changes
Hi Alex - no plugins using sockets - Business 9.6.1 - no other debuggers/editors in use or used (I have crashed/restarted LC a few dozen times today) - no remote debugging This is just a plain old stack, only a mouseup in a button, everything else in the stack script. I'm going to have to look back at my previous socket project to see what I was doing there that was different. It seems to me that this is what is going on: LC loads the script & the socket interaaction makes it impossible for any script change to be applied. Feels like the engine is simply not "letting go" in order to reload the script. Very peculiar, as I would expect that closing each of the open sockets would release whatever was bound and stopping the script changes from being applied. Thanks for testing & showing that it's something idiosyncratic to me.

RE: opened socket in IDE prevents script changes
While debugging in the IDE(Win 10 LC 9.6.1 VM) I have a socket client(plug-in) that had an open socket to the socket server on another Win 10 PC(metal running in a Win service written in LC also). I make changes in the IDE, save the stack and then generate an Android apk and the send the apk via sockets to the server PC that actually has the device connected and the server receives and installs the apk. I have never seen any problems with losing IDE changes or any IDE stability issues while in multiple debug cycles. I have seen the stack not being dirty now and again as Bernd documented in https://quality.livecode.com/show_bug.cgi?id=22555 . I've seen this even when not doing the socket thingy. I either add/delete a space or do a ctrl s to resolve it.

Hi Bernard, I have seen similar behavior of the apply button indicating "clean" when the script was "dirty"/had compile errors.

"do i understand it correctly that both, server and client stack, can communicate with each other using sockets in one instance of the LC IDE" Your understanding is correct.
