Thankyou. That did so many odd things that I don't know what to do with it. :)
Nice to see a fully worked example though, snippets don't always work, full
examples do, I wish they happened more often. :)
While I can do the area detection (already had to in some other project), this
is not really the answer. As you see, it takes a lot of ectra code. It doesn't
stop there either, I have to handle arrow keys, mouse scrolls, maybe even more
stuff, just to get a Spinctrl to work as it used to with NONE of this extra
code!
One thing I found was an UpdateUI event or some such. It forced update at all
times though, so it is a vicious cycle that detects its own updates, updates
again, chewing as much of my CPU time as ti can get a hold of. :) If I could
find somethingsimilar but a tad less trigger-happy it might solve this yet.
