Are you getting an ObjectError window with the Reset and Delete choices? If so, take a look at the file named in that window and you may find what mod you have conflicting with the behavior. If you can't tell from the file, attach it to a post here.
If you are getting a number of object error popups, you should probably run
Paladin's Hack Conflict Detection Utility. Also use CleanInstaller to scan your Downloads folder and take a look at the lines showing up in red. Those are mods that change global behaviors.
Neither HCDU or CI will tell you if there is an actual problem, just what may potentially be a problem. You'd need to select mods to remove and try again to see if the problem is fixed. Feel free to ask about anything you aren't sure of.
