RE: A Generic error occurred in GDI+
This seems to be a generic error meaning something failed within GDI+, commonly when trying to save an image that is locked, but that doesn't seem to be the case here.
A definition of GDI+ >> "Windows GDI+ is a class-based API for C/C++ programmers. It enables applications to use graphics and formatted text on both the video display and the printer. Applications based on the Microsoft Win32 API do not access graphics hardware directly. Instead, GDI+ interacts with device drivers on behalf of applications. GDI+ is also supported by Microsoft Win64."
You mention it is in the Sales Trx Entry window, what exactly are you doing when this error shows?
If you click on the 'Details' button, what does that show?
Do you have any third party products, customizations and/or VBA being used with Dynamics GP?
As a test, if you rename the GP directory on one machine, then run a Repair of Dynamics GP on the same machine which will re-create the entire GP directory under the original name, to include all folders and files, but without third party products, customizations or modified forms and reports, if you login to this 'clean' GP directory, can you re-create this same GDI+ error message?
--If not, we'd then want to add back first the forms/reports dictionary files and test again to make sure the error doesn't show. Then add back the third party products and customizations, one by one, until the GDI+ error shows again, if at all.
Let us know your findings or if you have any questions.
Thank you
