Recently some users reported an graphics issue when using PEAKS over Windows remote desktop connection. PEAKS GUI is not drawn correctly on the screen.
We have observed the same issue in the team internally and investigations lead us to believe the issue resides in Java Windows look and feel. I did some internal testing and it seems using the cross-platform look and feel solved the problem.
To make things easier for you, here is a modified jar file you can use to replace peaksstudio.jar in the PEAKS directory. Your PEAKS build number (go to Help -> About PEAKS to check) must match the build number of the jar, e.g. build 20131119. Please make sure you backup your original peaksstudio.jar just in case.
