what OS are you using? and what version of VMD?
the behavior you describe could easily happen from
an update to the graphics drivers or changes to
the configuration. also, what graphics hardware
are you using and what driver version?
furthermore, there are some OSes that automatically
update components of your system or can be configured
to do so, so i would 'never say never'.
