What do all these errors mean and is there anything that I can do to prevent/fix this

20 views (last 30 days)
While working in Matlab and running various code I have been getting errors at random times. The errors sometimes appear even while I am working in an editor and have not run any code recently. The errors do not seem to interfere with functionality most of the time but I'm not sure what they mean or if they are indicitive or a larger underlying problem. Any help would be greatly appreciated. Thank you.
This is an example of the errors I have been receiving

What version are you using? When I use r2007b I get things like this sometimes. It is odd.
It might even happen when I have had MATLAB open for a few days but not used it! I come back to it and the window is full of red, even though I haven't touched it. It has something to do with Java. I don't worry about it, just clear all,clc and go.
