weird behavior of webman

so, since a few days ago i was pretty sure that my 90nm rsx was dead, because was giving a bunch of 1601,1701 errors and one 3034 and 4432 error... so i was pretty unhappy about that....
then, casually, i remembered that all this time every time i started up my ps3 i was always activating the webman temp overlay....

so this time i tried to not use it... and behold... it works perfectly!?

i am the only one that experienced this problem or is a common issue?
