Shadowman,
Yeah, I've had virtually the same problem using CCleaner version 1.05.189 for the past several months running on OSX 10.7.5 (Lion) and have been casually keeping my eyes on this forum to see what, if at all, anyone has learned regarding this issue.
As a precaution, I always save ALL previous versions of CCleaner once downloaded. I too, am going to revert back to the previous major released version, which as I'm looking at my files appears to be CCLeaner version 1.04.148 or at least that is the only previous version I have. Which as a matter of fact I just installed while typing my reply here to see the exact version number. As expected, this version (1.04.148) opened IMMEDIATELY without a slight bit of hesitation or bouncing going on in the Dock. I certainly hope developers will be reading this to do some sort of compare between the two versions discussed here to hopefully learn what is their differences as to why they get stuck and never open.
A final note (observation), CCleaner version 1.05.189 will eventually open and function on my OSX version 10.7.5 (Lion), IF you let your Mac just sit and do nothing for about 5 to 10 min. Not sure of the exact amount of time, but it does eventually open. Is this reasonable, no, but it may be a useful observation in helping to resolve this problem.
Hope this helps.
At the time of this writing I've reverted back to CCleaner version 1.04.148 which opens immediately with no apparent problems running on OSX 10.7.5. I'm more than happy to make this pervious version available to all, if Piriform does not have a immediately available archive link to previous build versions.
Cheers!
Falofal
