Igor 7 Popup Contextual Menu Changes

Hello,

In Igor 6 I created a function for user's to filter their data based on some kind of condition. This involves using a popup contextual menu from a list box that gives the user a list of conditions such as greater than, less than, equal and not equal. I never had an issue with all items in the list showing up in Igor 6 but now that I'm testing it in Igor 7 it seems that only certain list items show up regardless of the order. Are there certain characters that can no longer be used in popup contextual menu lists?

Here is the code:

opts = ">;>=;=;!=;<=;<"
PopupContextualMenu opts

And attached is an image of what I see when I run the control. Only '>', '>=' and '=' show up on the list.

I have several other functions that use popup contextual menus but I haven't noticed any other missing list items.

Any help would be greatly appreciated. Thank you!
