Well, from where I am sitting, I can see a stuffed moose, a "Wee Coo" (the wonderful Scottish Highland Cow), a koala, a rabbit, a Fire Chief Bear, a picture of lots of teddy bears, a fantastic poster of a mother Panda and her cub, but I do not see any monkeys....
1. I needed to do some maintenance that required a reboot; after doing that, I had problems again in getting PWM to show up in FF.
2. I downloaded SeaMonkey, closed FF, installed SM.
3. I installed PWM in SeaMonkey, restarted PWM. Results: Perhaps two seconds to get PWM to show up with Ctrl+`. Created one account; it took perhaps three seconds for PWM to close. Restarted SM, played with PWM, not much to report. However, I did notice one thing which I'd not tried once I started having PWM problems: With PWM open, if I went into an account, if I hit "Cancel", PWM would close immediately. So, PWM is faster with PWM than with FF, although still not instantaneous.
4. Closed SM, restarted FF. Tried to bring up PWM; noticed the hour-glass cursor momentarily, then PWM appeared in perhaps three seconds. Edited account, closed PWM; less than previous attempts, perhaps a second quicker.
While writing this, edited a PWM account; eight seconds to close. Restarted, removed spurious edit, eight seconds to close.
I am still suspicious about FF 2.0.0.5, with NO proof of any sort whatsoever that there is any such interference between FF and PWM>
I know of no problems with either my computer or the OS: Both have passed numerous tests recently, and no other FF extension, for example, is causing any problems, nor are any of my other regularly-used programs.
I think I'll post this and go looking for monkeys....
