Hi I keep getting a spontaneous crash in LT2002 in various situations such as copy / paste etc. after which the plot preview windows' fonts appear in outline and also ends up plotting the same way on my HP Designjet 800. I've found that uninstalling and re-installing LT2002 with the update patches sorts the problem, but does anyone know how to permanently cure this crash? ( I use Windows 2000 Professional...) Thanks in advance.... Chris
