I am having an issue when trying to run most programmes in Windows on my mac via parallels. Whether it is Corel Draw, Sage accounts software or just Internet Explorer, every programmes seems to be unresponsive and will eventually just freeze or crash. I have tried increasing the memory space allocated to parallels, this has made no difference. I have tried reinstalling parallels tools, unfortunately this process also freezes. I am not aware of anything that has been done that would have changed any settings and am at a loss as to why this is happening. Parallels usually operates without any issues. I currently have Parallels 9 build 24172, there are currently no updates available to the version I have. Any Ideas?
