Thanks for your help,

that did not work, I can not reposition the window at all. Now I have a new problem, whenever I try to open the BSW, I can log in, but once I have logged in the window is just white. If I try logging in from the website, the window opens but is corrupted, so I can only see some square shaped forms. I have reinstalled Java on my computer and that didn´t help. I´m sure I have a virus (or had) on my computer, a scan says it´s clean (the scan found a virus but deleted it) but I think either it´s still there and is still doing damage, or it already did some damage before I deleted it after the scan found it.

Any suggestions are welcome!

I had a virus in my computer that interrupted my java,resulting in a problem that changed the window size of the BSW window so I could not chat there anymore. I reinstalled Java and the BSW, but the problem is still there. When I log in, a really big window opens where I can not see anything (full screen window) but if I blindly log in, it works, but the window size is still a problem so I can not chat. Does anyone know how to solve this problem?
