MMX 14.0.4 can't open Unit Dependencies with Delphi 10.2.3

[ULIK 16]

Hi!

 

I noticed a bug on MMX 14.0.4: working on Delphi 10.2.3 I can no longer open the unit dependencies dialog as this throws an access violation:

I checked it again with MMX 13.1 and here the dialog opens fine again. If it is related: IDE designs are deactivated on my Delphi installations.

 

kind regards,

I've done a test: if I enable IDE designs, then it is working again with 14.0.4. But it would be fine, if you find time to fix this (I prefer to disable the designs ,as on Windows 7 I find this better readable)

 

Thank you,

Ulrich

To be honest, I usually test only against an IDE with all options at default. It is near to impossible to test for all combinations. It was my hope that such things are discovered during the beta phase.

You are right, this is not possible, and the main problem in these case is the IDE and OTA. Should work independent from the themes 

[Uwe Raabe 2059]

Well, the OTA contains a few special interfaces regarding themes and the Unit Dependency Analyzer was the first form (or better frame in this case) making use of those. What I didn't know (because as usual those things are poorly documented - if at all) is that it seems to be forbidden to call ApplyTheme when IDE themes are disabled. Not that this could as well be caught inside ApplyTheme (just for safety - instead of crashing), so that not everybody has to add this additional check in their code.

Don't worry. It's fine to test against the defaults only. For all the special situations we have that group here to post the problems
