Hi Mark,
If 1.8.7 works well, there is no reason for 1.8.8 not to do the same on the same machine. Both versions share the same graphics engine, which is the only thing that can cause problems on Windows (not on the rest of platforms).
At any rate, upgrading to version 1.8.8-1 is absolutely essential if you want to keep in synch with the next tools and features we'll implement during the coming months.
