x-lite movement on desktop

[hubert_2711]

Hi ,

I am using x-lite , but after some hours that is open on the desktop it begins moving on the desktop .
For example i open it and place it on the centre of desktop , but after some hours when i return to my pc , i find it on the right side of desktop .

why ? please help me to resolve , it is important for me that the window of x-lite remain in the saim position .

thanks
