Windows client crashes when switching to and from Excel

(0) ShareShare
ReportReport
Posted on by thegnic 75

Hi,

We have a couple of clients that are having similar issues where by their Windows Client crashes when switching between BC & Excel. THis can simply be when switching bewteen apps or when copying/pasting from one to the other. Once of my colleagues suggested it is a known issue with no fix - surely not.....

Does anyone know of this and if there is actually a fix?

Versions vary from NAV 2016/17 to the latest BC.

Thanks

Gary

    Hello,

    Does this issue also happen in the CRONUS company on the same machine?  Try to re-compile all objects and ensure you are recent with your maintenance plan and CU upgrade cycle.

    Thanks.
