Hi everybody,

I have a very big problem with my applications and I do not know where
is it!
I am developing an applications since one year and now it doesn't work
on some pc.
The application have a standard TForm with a TPageControl each page of
this have a frame.
The applications when starts draw the mainform and starts a program
manager then when the user press a button a program manager launches
three threads. The first one save data and print a lot of information
on a frame on the maniform, a second one run and wait for a compute
command, the third check a queue of commands and save on the DB the
related information.

The problem is that after the application compute in the second thread
I am not able to minimize the form, move it or take away the focus the
applications crash and I have to restart it.

The computation perform a get from the first thread data structure and
do some operations then push information and a command on a queue in
the DB thread that process them when is able to do it. I do not try to
minimize the application before the end of the operations but it do not
responding and I must be stop and restart it.
This problem do not happen on all PC but on my desktop pc (3GHz no SV)
and my notebook
my friends with his hyperthreading pc is able to run it without any
problems.

Thanks in advance
