Ressetting the dialogs fixed my problem, then I tried to reproduce it, and with the r190 it happen again:
1. Import a sprite of 30x30
2. Put at full-screen in the secondary monitor
3. Suspend the Pc and turn it On
If you want me to give my Pc specifications, here they are:
Amd Ft-8150 Eight-Core-Processor 3,6Ghz
Radeon AMD HD 7850 2gb
Anyway it works fine with r194.2
