Current release version: Lazarus 0.9.30.2RC1 r32563 FPC 2.4.4. (Qt or GTK, the error appears in both).

 Confirmed with fixes_0.9.30.1 and FPC 2.4.4 on OpenSuse 11.4 Linux + GTK2, running under VirtualBox.
What more, I can also reproduce it with Lazarus trunk in the same environment.
On Windows it works correctly.
So, this is clearly not an issue of fixes_0.9.30.1 but something else. Why others can't reproduce it on Linux, I don't know.
I will set the target back to 0.99.

Silvio, could you also test with Lazarus trunk using the same environment.

LazTarget should be 0.9.30.2, if the issue does not exist in 0.9.30.

LazTarget must be 0.9.30.2, if the issue does not exist in 0.9.30 and does not exist in 0.9.31.

I confirm that this bug exists ONLY with gtk2 in laz trunk, but not with qt.
@Silivio, are you sure that you can reproduce this with qt ?

Yes,

I will create a Virtual Machine with Lazarus/FPC trunk to reproduce this error in Qt.

I cannot reproduce this with trunk (Fedora 14, 32bit qt-4.7.4)

Please test with TRUNK and close if ok.
Unfortunatelly we cannot fix it for 0.9.30.2 since there was many changes about TabControl in trunk.
As workaround for 0.9.30.XX (gtk2), disconnect OnExit() of all controls on TTabSheet, and connect it again in OnShow() event of tab.
I cannot reproduce it with qt in any version.

I cannot install Lazarus trunk on my openSUSE (in Virtual Machine).

You could send me a patch to I apply in my RC1 copy?

developer   ~0053289

@Silvio
1.That patch cannot be applied to RC1 since there was many changes about TCustomTabControl (it's renamed).
2.You can get patch here

Sorry guys, now I saw that my Lazarus was compiled for GTK. ^^'

I thought that being in an environment in Qt, the Lazarus was already compiled for Qt.

After compile Lazarus to Qt, I saw that the problem did not really exist in it.

After this fix the problem was solved for GTK.

Thx.
