hi leonie and william.
thanks for the help here.
i just started up aperture and noticed this thing again. it is really odd in that i think it is located in the same spot all the time and also that i see it when i minimize aperture. it is not there when i close aperture which i suppose is an indication that this is software specific? anyway.
i had thought that i was posting this time in the Lion forum so i am not sure if i made a mistake here or if the post got moved or something. in any event from everything i can gather over here in running tech tools pro and disk utility my primary disks seems fine (i have my OS on one drive and store my data on another drive) and it was the internal /backup/ of my OS drive that was failing and which has since been replaced.
anyway, i am typically overloaded with computer and other things to do and i am regretting that i am not sure i will find the time to install Aperture on a test OS. i am hoping to upgrade the desktop at some point soon and i have to spend time on getting back an XP installation to get some old software working again as well.
in short my apologies for reposting. i thought i was looking for generic OS troubleshooting help.
do you guys think this is something that needs to be pursued more aggressively on my end? i ran the less invasive "refresh" option in Aperture not too long ago (i forget if what this is called but i did not do the more aggressive option as the documentation seems to suggest not doing this unless absolutely necessary...) and while nothing seems to be wrong i don't want to overlook this as an indication of some kind of warning.
THANKS
