WSPR not decoding

I run WSPR with an ICOM 7300. I've noticed that when I'm actively watching the screen most of the signals I see on the display get decoded. However, if I start doing something else with the PC, or just go for a coffee, when I return most of the signals have not been decoded, ie. there is a big gap in time when WSPR did not see anything even though I can see strong signals in the display. As soon as I start watching the screen again, decoding returns to normal. The PC is not sleeping during these intervals, so I'm puzzled as to why this is happening. Help!
