I have been using profiles I made with PrintFix Plus for a long time
and recently moved to a LCD monitor.  I went to launch PF Plus to
adjust a profile and the program will not launch.  I have not made any
recent changes to my computer which runs Windows XP.  I tried
restarting, reinstalling and even downloaded Ver. 2.1, but it still
will not launch.  A task bar button will appear, but it has no
function, left or right mouse clicks have no affect; I have to use the
task manager to close the button.  
Has anyone else run into this problem?  Any ideas?  Thanks in advance
for your help.
