Corel Draw X6 - "processing" bar blocks fill & stroke.

I don't know if this is a bug or a feature. My Corel X6 is sometimes having problems with saving files or copying things from one file to the other, a "processing" bar appears on the bottom right corner. It takes ages to "process" (whatever it is processing) and it's blocking access to the quick stroke and fill changing. Its really annoying cause I often work on multiple files at the same time and I can't quickly change stroke/fill of stuff in one file cause Corel is "processsing" something in other file. I have no idea if there is a way to fix it?

I have a screenshot (I have Polish version so "Przetwarzanie" is "Processing")
