Just noticed this in the last few weeks - not sure if the latest DO update caused this or what but dopus.exe is using 100 percent of one the cores in my i7. I ran procmon on it and there are number of dopus file i/o events that are getting errors.
Process Name: dopus.exe
Result: INVALID DEVICE REQUEST
The drive F: is a fast Intel SSD in RAID0 which may or may not have an effect.
I shut off Norton AV and that didn't make a difference at all.
Any ideas to help fix this? This is extremely annoying.
