In running 5.0.1 I am seeing problems using CVS diff. When running a
"Compare with latest repository version" IDEA hangs for a considerable
amount of time trying to run a 'checkout' command. I never experienced
this issue with 4.5.x and there have been no changes to/with our CVS
environment. I am running JDK 1.5.0 update 4 with IDEA build 3496.
