Hello,
There is a problem which I had and maybe a lot of you can have too.
To reproduce the problem you must have Office 365 installed or maybe any software that uses Visual Basic for Applications in it's latest update and try for example using CalendarWizard extension or entering macro editor and trying to work with forms. The next time you open CorelDraw and try using CalendarWizard/edit forms again the entire program will crash with "not responding" message.
To solve the problem for the next time you open the program you must move/delete the .box file in C:\Users\<username>\AppData\Roaming\Microsoft\Forms\CorelDRW.box or C:\Users\<username>\application data\Microsoft\forms\CorelDRW.box .
I've seen this in another vba-related thread from Microsoft Community Forums and although it's not a permanent solution it probably can save lots of time from users having this problem.
(if you want to look there too the link is https://answers.microsoft.com/en-us/msoffice/forum/msoffice_excel-mso_win10-mso_2016/office-2016-crashes-when-userform-added-to-vba/f2f16ffa-9a1f-4bfd-babb-1e93a78d5c65?page=2 )
If someone finds a better solution to this problem please share, thank you and good luck!
