Almost all of these roms and themes are provided by private individuals who also have jobs and lives... they don't provide support officially. I am not sure why you would have that problem... I have 5.0.7.1 with this theme installed and can't reproduce your problem... I imagine the theme developer will have the same issue... it's probably not the theme causing it.
I understand about them having lives but I also saw him posting last night in the froyo side of his themes.
NP's with that ...froyo is the latest and greatest.
I just came back to post though that I accidentally fixed my problem.
After having to keep flipping the screen timeout times around today I finally got fed up enough to have rom manager take me back to the stock non rooted 2.01 rom I checked off to have it wipe the data cache before it it rebooted and started clockwork.
Well clockwork failed and I choose to reboot, when it came back up and rebooted back into blue energy the screen lock is now working.
I still plan on going back to stock though, fussing around with all these bugs is a waste of time. Not to mention my wife who has been pissed at me for screwing with this when she wants "me time".
Sorry about the long delay for an answer. Yes this theme is still supported, but even Koush will be coming out with a new version as soon that is based off the Froyo source. So..at some point soon it won't be supported, until a new version of the theme is up.
Sorry you were having problems with it. I've never had problems with the lock screen, and I am a habitual 'screen locker' when I am done with it to conserve battery. Sometimes reinstalling helps out if there are random bugs like that. This is the first I have heard about a bug like that though.
That said, I have a thread on CyanogenMod Forums, this thread, a Bugless Beast thread, and the Froyo thread to keep up with. Sometimes for some reason Droid Forums stops emailing me updates on a thread. I have asked for a section to keep everything in one place which would help me answer everyone's questions quickly but I haven't gotten the final response as of yet.
Obviously there are more support like questions going on with the Froyo version as that is the hot topic right now. I consider the Bugless and CyanogenMod versions to be pretty stable so I don't check them as often.
