I assumed your RM9 is version 9.1.6.0–what version of Windows are you using? If this just started and you’ve had RM 9 for a while with no or few problems, what has changed lately?
This link from Jerry explains more abt DropBox
As to Access Violations and Argument out of range - there are different ones that happen in RM9 and RM8 which is why I was asking abt what you were doing --some take a while to happen such as using the arrows next to a person name and or moving up and down the index–clicking on names–usually happens between 650-1000 clicks-- others happen very quickly such as when you go to descendant view and click on the up arrow to go to the father of the person-- usually happens within 8 clicks.
Besides pausing DropBox, I would run all the tools-- then even reboot the computer- this won’t stop it BUT MIGHT slow it down for a while-- might also try just one monitor BUT don’t remember any errors in RM 9 due to dual monitors…
If you can’t tell us what you are doing , then use the search box above and do a search for Access Violations and Argument out of range-- read thru them and see if any sound like your situation-- if so read the whole thread to see if there is a work around listed…
As for does RM 10 fix this? NOT sure-- there are NOT as many Access Violations and Argument out of range reported on here with RM 10 BUT ???
