 I have a bizarre problem with my Apple IIc.  I have run "Master Diagnostics IIc" on it several times but it checks out on that program.  Anyway, after I run the computer a while and I'm in double hi-res graphics, for example, "Dazzle Draw", the screen starts to flash and mess up with a lot of snow and a totally illegible screen.  But when it accesses the disk drive while the screen is messing up, the screen comes back clear and legible.  This problem only happens after I've been using it a while.  Is this
 a heat problem and does anyone else have this happen?  Or is it just my computer??  Any suggestions? Thanks in advance for any help.
