display issues after doing update on parallels 8

I am still on parallels 8 and did an update with reboot but now my display is all goofed up. The only way to increase the size of window is dragging the corner. I don't want it to do this. I want to be able to widen and shorten manually so I can still use the other half of my monitor to open other windows. If I shrink the parallel window so that I can have multiple windows open the font becomes so small I can't even read. I know there must be a simple solution but I can't figure it out. Please help!!!

 

Hi Howsa6

Please reinstall Parallels Tools as suggested at http://kb.parallels.com/4841
