hi

sometimes my application restores itself, with 6.31 when that happens, i see a blank main form as you can see in the attached image. this didnt happen in previous versions. as you can see only the caption is visible, the form itself is blank and the status bar isnt there at all. i must add that the problem happened with 6.30 as well but i thought it is related to the minimize problem that u already fixed.

im not sure what exactly causes that… if u can give me a hint on what might cause such a thing i will try to make a demo
thanks

also, sometimes when moving from normal to maximize window, not all the window is repainted immediately u see the caption and statusbar ok, but the content of the form is still as it was in normal mode, clicking anywhere – makes it draw everything

attached exe+ sources
running inside delphi made the problem appears quicker. running the exe outside delphi i needed to maxim/minim several times for the problem to appear.

open Delphi, run the project and maximize, wait for 5 seconds, if nothing happens, set it back to normal and then maximize it again (using the same caption's button). at some point, the whole form will become blank.

if u r lucky u will even get a stack overflow when u set the form back to normal in one of those times.

Thanks for demo, I'll try to solve this problem in the nearest release.

im sorry but the problem is still there

open the attached demo (previous reply here) and compile it and run.
set it to be maximize.
click on “show desktop” icon (quick launch of windows) – it will disappear – ok
click again on show desktop icon – it will show up partailly or whole form blank – just the caption.

playing a bit will maximize/normal using the button/doubleclicking the caption will result in stack overflow error.
the stack overflow happens (when it happens) when clicking anywhere on the caption

im still playing with it to find a “rule” in this behaviour but u can try the above in the meantime

it seems not to be related to the extraborders. even with this prop set to false, the blank form happens

This problem happens under Aero?

[emailaya]

what do u mean aero? the skin?
im using Office2007blue
not sure about the other skins

im using XP not vista – not sure about vista

the steps i wrote here were for partially painted form but on my computer (and other users) i get blank form a lot. the thing is i dont know what causes this in order to make a demo for it.

[emailaya]

i was wondering whether u encounter the problem i reported here (blank form) on your side as well

Thank you for info.
This problem is not easy for reproducing but I think I see it now, but I see a piece of Memo also (part of client is visible)…

[emailaya]

in my project i get the blank form problem a lot of times. because i dont know how to reproduce it i tried to play with the demo i already made previously and the closest thing i got was the partially painted form. i hope the reason for this is the same reason of the blank form i have in my project.

i can show u the problem of blank form with teamviewer, the question is whether it will help u understand what causing it. maybe the dfm of the form can help u?

i hope that understanding the partially painted form will solve both problems
