Yup, I am aware that it causes problems. However when it freezes there is not much I can do. If it hasn't sorted itself out in a few minutes it is obviously in some sort of deadlock. So, the issue remains. Can a mod clear this for me somehow?
Went to bed last night with the issue. Got up this morning and can't start any still with the same issue. The client had a forced shutdown since it froze, I think that is what caused the issue.
Runemate will not close nicely on my computer -- occasionally it freezes indefinitely and when I relaunch it it thinks I am still running 2 instances. This issue fixed itself the first time or two it happened but now it has been 12+ hours and the system still thinks I am running 2 instances...
