From time to time I noticed on my N9 that the wallet application (paid version) needs about 10-12 seconds to open, meanwhile I the system, is compalining that app is not responding, prompts to close it or not. Choosing No, then after a while e.g. 10sec the application opens, still though it's quite slow to respond on browsing entries. The rest of apps seems to respond resonably OK, and I have not noticed any heavy load on the system. rebooting does resolve the problem for a while. Any ideas?
