There is currently a bug affecting a small number of customers that causes a crash when attempting to create a new button in the Boardmaker 7 editor.
If you attempt to create a button and get a crash error that begins with 'attempting to divide by zero' take the following steps.
1. Select the file menu in the editor and go to User Settings
2. Select Interface on the left
3. Change the grid spacing setting to a different number (except 0)
Once you change the setting and save you can go back in and set it back to what you had it at prior and it should be ok after that.
Please contact Technical Support if this does not resolve your issue.
