WebGUI error in context menu

Hello!

I am using the SAP GUI for HTML for some transactions (e.g. pz02).

If I am opening the context menu (right click in the window) and select "Help", a short dump appears:

Runtime Errors: ITS_EXPRESSION_NOT_NUM

Template "templates/webgui/dm/generator.html" has triggered a runtime error in function "topinclude".

Cause of error: "ANONYMOUS113" could not be converted into a numerical value.

I have not found any SAP OSS or forum threads to this topic...thanks for any advice

Best Regards
