Hello all
I'm developing an application by using Qt since version 4.4.3 until 4.6.2 and it will take maybe to next year.
I have a strange problem.

I've to handle mouse move event and do some task. It's OK on my developing computer and some other computer. But yesterday I installed my application on a new computer and mouse move event handler did not work.

This is that computer specs: Core2Duo, 4gb ram and it's os is Fedora 12 and Debian 5 also Sabayon 5.2.
My developing computer OS is Debian 5 too.

What is problem source?!
thank you all
