VST connections

F4 or via devices vst opens as a narrow unreadable strip that can not be re sized. I then have to click always on top to open it. When open if I go to resize it it reverts to the stick window, and it will not save , so each time I want Vst connections I have to click the always on top tab. Also all my presets have gone. This occurs on new and old projects,I use a pc with W7. If anyone can shed some light on this matter It would be appreciated
