On the blank desktop part encountered this several times in the last two days.
Discovered that I had to go to the monitor resolution icon (the one with a screen with the diagonal arrows on each end) on the top tool bar.
Select match resolution and remote computer screen came up then.
Another little info:
if I configure LogMeIn to download and install updates automatically, does it that silently?
does it keeps all my configured options?
I don't want my customers abort the update by mistake or click any wrong button.
