So I tried logging on and off several times, this didn't help. Having logged in I can open another tab and don't need to log in again, so this is working.
Then I checked the cookies my browser saved from pool.biblepay.org and I think I found the mistake: the credentials_password cookie saves a wrong value for my pw (double-checked this by deleting it, logging off and on again, same mistake). The problem seems to be that my pool-pw uses a semicolon ( ; ) in the middle of the word and this seems to create a problem for the cookie, because the cookie-pw stops at the letter before the ";". I will try and change my pw again without diacritical signs and see if that helps.
One of my computers just crashed again, I disabled SSL, let's hope for the best. :-D
Edit:
Oh, you beat me to it by posting the update, I'm gonna give this a try then, let's see how it works out over night.
Seems to have worked as expected over night. I tried 3 different things:
a) one machine with 1.0.7.5 and SSL enabled --> crashed
b) one machine with 1.0.7.5 and SSL disabled --> worked
c) one machine with 1.0.7.6 and SSL enabled --> worked
So this was definitely and solely an SSL issue, which is fixed in 76; thanks again.
Regarding the pool login: now without the semicolon in my password the pool page works like a charm and does not kick me out every couple of minutes, so problem solved I guess.
Only "problem" remaining is: why is the (only existing) pool hitting less than 20% of the blocks.
