It was the Java! I reinstalled Java 6 and it worked fine!
Guide GUI's are all blank gray boxes, something is wrong....

Well I have an issue with Guide GUI's. I will run a GUI based program and it will display a gray box the correct size, but it has nothing in it, all the buttons or displays or plots do not show up at all. It remains an empty gray box...
I have tried a few different GUI's and even made one with all of them having the same result. I run MATLAB on a linux, I know I have had the GUI's working in the past, but now they don't. I'm not sure what changed, it could of been in an automatic update, I don't know.
This is a post found that looked similar, but it did not seem to really answer how to fix the issue:
It happens to all GUI's so I did not think I needed to add code. I did try looking it up too, I found others with the same issue (it looks like it could be some type of Java issue, but I'm not sure), but did not really find a way to fix the issue.
Any help will be very appreciated!!!
Please if you know how to fix it, let me know!
