This most likely due to a graphics card issue. Try to go to the Operating System specific help forum and look through the most common issues
Sticky Threads. I'm guessing Windows here. The most likely source of the problem is either a Graphics card or RAM issues
Where you choose the forum press Technical Support, and then the forum that has your operating system.
There is general Windows support, General Mac Support etc.

Remember to (unlike bdalekid) to give the necessary info when posting a new thread. Like in the very first thread here, only more related to the video hardware and software your computer has. Don't be afraid to even include things that at first glance will seem unnecessary. You should rather give too much info than too little info.
Also include Java version (you can see it if you in Limewire press Tools and then about limewire) or in add/remove programs. Can be the source of the problem although highly unlikely.
