I don't know if this is a K2 issue, or a JCE issue, or other. I thought I would start here though. I have a bunch of content in K2. I am wanting to open items in K2 Add/Edit Item. I make some changes. Then I click on the "Add to Menu" icon which is in the upper right corner and I get a popup. The trouble is I have a large set of nested menus in K2 and I get about 30 characters of width in the "parent item" field of the popup window. I would really like to make that window wider. Any advice?

Sorry, I was confused. I didn't realize another admin had added the Add To Menu plugin. I thought it had appeared as a packaged item to another plugin such as K2. I will go bother their forum.
