8624	Exception when second monitor is activated	anonymous	anonymous	"What steps will reproduce the problem?
 1. start JOSM on Win 7 with only primary monitor activated and work with JOSM 
 2. press WIN+P and choose extended (so both attached monitors are active)
 3. exception message appears

What is the expected result?
no exception message

What happens instead?
exception message appears, JOSM continues running normally - the message is just irritating and seems to have no real meaning
