what is the actual problem ? it seems that you can close the quick tabs so what are you trying to do when the problem occurs.
while i will try to solve the problem for you please understand that 2002 is a very old version of quicken. it has not been supported for some time. the answer may very well be that you need to purchase a newer version of quicken
when software is not supported it means that if an operating system is upgraded ( and xp will do this automatically ) if the old quicken has a problem with the xp upgrade quicken will not bother to fix it.
if it worked recently you can try doing a system restore. this will not affect your data but it will put the programs and registry information back to the way they were on the date you choose for the restore
start menu / accessories / system tools / system restore
select restore to an earlier date
you will get a calander with various restore points for each day
choose one for a date BEFORE the problem started
hit the ok /restore button
the system will start to shut itself down and a blue status line will come up in a box saying restoring your system settings.
when it finishes the system will restart itself.
hopefully everything will work the way it did on the date you selected
