Spark 2.5.4: Freezing

Maybe it’'s related to http://www.igniterealtime.org/forum/thread.jspa?threadID=25904&tstart=0

But maybe a bit different. Sometimes, especially after workstation beeing locked for a long time, Spark chat window stops to respond. I see new messages coming, i see last selected tab, but i cant switch to other tabs, i cant put cursor in typing area, chat window titlebar is gray. Most of the time such ‘‘locking’’ is solved by bringing up roster window. After this chat windows starts to respond. But this cant be fixed at once, i cant bring up roster window for some time. Really annoyning when you see new message and have to type your answer quick, but spark is not responding at all.

Same resolving is with chat window drawing problems. Sometimes it doesnt draw chat window correctly, titlebar is dissapearing, but after bringing roster window up all is ok.
