Hello,
I have a relatively complex, multithreaded application, compiled with
lazarus 1.6.4/fpc 2.6.4 (it's the same application I reported in
fpc-devel having a problem with tthread.synchronize but I cannot find in
in the archive right now, the thread was "Suspicion about
TThread.Synchronize").
The customer is in the process of migrating their PCs still running
windows xp to windows 7 (yes, I know, I know...)
In this application, and this application only, upon the switch to
windows 7, a call to MessageDlg hangs for a long time (around one
minute) before returning. I saw that on my development machine but I
didn't mind since on the target machine it ran fine (when it was running
under windows xp that is).
It's not MessageDlg itself (in other applications migrated to windows 7
and compiled with the same lazarus/fpc versions we don't see the
problem), but some strange interaction with my application, alas I
cannot find where the problem lies.
If I recompile it with lazarus 2.0.2[*]/fpc 3.2.beta (cannot use 3.0.2
due to the above mentioned thread issue) the problem disappears.
Any idea?
[*] would somebody pleas take a look at this bug? The solution seems
simple but I'm not sure it's correct.
