Aqua-Soft Forumshey,sorry I didn't read the whole thread, but when I hit the button to hide any category, it resizes the window - but also in the width! So if I choose to hide three categories, I haven't access to half of the content of the interface
Thank you for your report, I'll look into it.
Something similar was reported once before, but still I cannot reproduce this. Sorry, I can't fix it until I find out everything. This feature relies most on Delphi's TForm Autosize property, I don't do the size changes by myself. The problem might be because of large fonts, enabled in your system, but I had large fonts enabled on the first machine where iC2.x development started (that machine has actually died already). Everything was fine then. Now I'm having iC2.x on my laptop without large fonts - but things are OK.
Anyway, I was planning to remake this feature - it misses smooth animation very much, I think. (Aqua spoiled me 
)
