Morphing of Icons in JSwat 2.8

Hi,

I'm using JSwat 2.8 on WXP and I get problems with the icons morphing or disappearing after JSwat runs for a period of time (sometimes 20 mins, sometimes several hours).  This occurs with icons throughout the product including toolbar icons, menu icons, and so on.  The toolbar icons will turn into some type of square and all icons will look the same so it is hard to discern which button is which.  Is this a known problem?  And is there a fix?  I've pasted some diagnostic information below.

thanks in advance,
Max
