I have the same type of problems, espcially since upgrading ruby and watir. 
I know its bad prctise to rely on sleeps but in reality I don't have the 
time to spned tweaking the code to cope when a sleep will to the trick. In 
fact sometime I need to sleep even after a wait for a certian element. We 
are only writing test apps anyway, not production code.

Basically, sleep = bad but I don't care it works.
