I'm sorry, this will be a no-code question, but I think it is still the right place to ask. I'm using the (unfortunately) not so famous language APL and am having problems running my apps under W10 - the forms are shown without a caption: form without caption

Only when I switch focus to another app, it gets visible: enter image description here

So, without going too much into the details, has anyone come across this before (in other languages on the Windows10-platform) and are there perhaps any new settings or events that need to be considered? (I discussed this with Dyalog, the developers of that environment, but they seem pretty sure that they are unable to address this...)

  • Does your code do anything with the non-client area? I ask because that is certainly not using the defaults. Consider adding the winapi tag to this question. The people that frequent that tag may have seen this before. – theB Sep 15 '15 at 13:43
  • Thanks for the winapi-suggestion, have added it. As far as *my code* is concerned, nothing is being done with the non-client-area. Perhaps the APL-Environment does, but as a dev I wouldn't know that or couldn't affect it (I assume)... – MBaas Sep 15 '15 at 13:46
  • I would try a caption of just "Betrag" (without ö, ü, usw.) just in case there is some strange encoding going on. – Lobachevsky Sep 15 '15 at 13:55
  • Been there, done that, did not change ;-) – MBaas Sep 15 '15 at 13:55
  • @MBaas - I assumed that you weren't doing anything with the non-client area, but I had to ask anyway. – theB Sep 15 '15 at 14:18
  • *"as a dev I wouldn't know"* - That's a pretty odd statement. If not a developer, who else would know? – IInspectable Sep 15 '15 at 15:20
  • I'm an APL-Developer. To interact with Windows, I depend on the commands the APL-Implementor provides and I do not need to understand the mechanics of these when using them. To me, that does not sound odd, but describes anyone not working in bytecode ;-) Sometimes there is a rather high level of abstraction between dev and bytes (as in APL, fortunately), sometimes it is thinnet (C). – MBaas Sep 15 '15 at 15:27

I've been struggling with this for wks now, but suddenly I found the solution: I was using a '3D'-property of the form (set to value 'Dialog') and when I removed this, everything looked good :-)
