finding what the program running is

[unwashed potato!]

every now and again i am getting box pop up on the taskbar (im having a really dumb moment and im not sure if its called taskbar? the bit at the bottom with the clock lol) the trouble im having is that i have no clue what it is as it only pops for up for literally a second and theres no name and the picture is of like a program running, its a white box with a blue line at the top.
nwo how would i go about finding out what this is as its only for a split second that its there? i have run spyware and hasnn;t made it go
