Hi, The workarounds available are either set the scaling to medium/default OR change your "Windows Display Settings" back to 100%. I'd need then specific error information to provide additional detail.
Thanks

1st error message:
Error in definition of screen item: PHEADER 0184
Error #29: Invalid Mnemonic or position specification
Name: SALESORDERNO @(83,25)
CTL value: 10031
[4230]

2nd error message
Error 65 Window element does not exist or already exists
Program: _WINPROC
Statement: 6583
Class: SO_Invoice_UI

Hi, If the customization involved resizing of the screen, reset the screen back to the default size and retry. Verify all customized buttons, fields etc...are in a visible area of the screen. Have the user access "User Settings" from the Launcher Bar - if an error 29 occurs there you have the 2 work around(s) listed above. The issue is corrected in the 2018 release scheduled for later this year.
Thx
