Right Click Contect menu is off

When I highlight multiple objects and right click them in the local browser, the options are messed up. I use notepad ++ as my default editor. When I select multiple files to open them all at once, I right click and choose edit with Notepad ++, dreamweaver is launched. I thought I clicked the wrong option so I tried it again, and sure enough, Dreamweaver is not even an option but it opens it anyway. The top option is bolded and says Edit with Notepad ++ even though that's not really the option.
I figured out that if you select more than 15 files at a time the menu is not right. 15 or less, it's correct.

Thanks
