I’m trying to make an AJAX site that makes heavy use of objects (maybe
my first mistake =( …). I’ve come across a bizarre bug when using IE
6 where objects don’t seem to go away after leaving a page! Any help, insight (solution =P ) or empathy is greatly appreciated!
At first I thought it was some sort of memory leak [closures or circular references] … but I diagnosed with drip [and it came up clean]. Also, it doesn’t seem to be related to IE caching (since even with my IE6 caching turned off, I still have the problem).
An example of it is below:

To replicate the bug, go to the site, press refresh (or F5) multiple times. At each refresh, it appears that the objects take longer to create!… For test 1 through 3, the times stay generally consistent. However, for test, 4 and 5, each refresh adds about 10-20 ms! Strangely (or expectedly), it doesn’t cause problems in any version of Firefox or IE7. I’d ignore the problem, but it appears ~30% of users are still using IE6 [and it would be a fallacy to ignore them]. Any help would be greatly appreciated… as its driving me crazy!
