Strange to see that not much was going on - procmon with tracking all activities showed only "Process Profiling" operation all the time, like nothing is happening. I then launched procexp - similar situation for which I captured screen-shot: http://imagebin.ca/img/KaEQGEuv.png
Now when I tried to get back to salamander (after I done above) the window couldn't show up and even Alt-tab didn't work. I switched to procexp and killed the salamander process. After restart I saw that operation wasn't successful (I tried to rename file initially) and interestingly AS didn't asked about deleting previous instance of temp config file, neither it opened panels in folders where I was last time (logically) and even more interestingly I could reproduce this issue couple of times*: go to that particular file, in-line edit and paste the name to rename it - salamander locked. Not exactly locked as I can do other things in AS but started file operation got locked.
*I could reproduce the behavior, but I tried one more time now before posting and file got renamed without issue

As I said this happens quite randomly in a manner that I can't see any obvious pattern why this is happening. And if I let more time (it's half minute to minute usually) the operation will complete, but something is wrong or course with latest version on my PC at least
Any ideas?
