Hi SLKDS,
Could you tell me which version of InfoPath are you using? And you said >>working on exciting InfoPath file <<, was this file a new blank file or a created file? If this issue only appeared in a particular file or in all files? Have
you ever tried open a new InfoPath file in safe mode and check if it works fine?
First I suggest you try to use Alt+Shift+F12 shortcut and check if the Code Editor can be opened correctly. If it can't be opened and pop up with error messages please post the error messages here.
Then try to open the file in safe mode, if it works fine try to disable add-ins in InfoPath.
If this issue only appeared in a particular file, if possible you could send this file to our email address:
ibsofc@microsoft.com I'd like to help you check it.
Please Note: The email subject you should use the URL or the Title Name of your case.
I need more information about your issue, please be a bit more precise explain your issue and tell me the steps of creating or opening a InfoPath file, so that I can get more accurate solutions to this problem.
Regards,
Emi Zhang
