Hello,
Actually, its happening when the layout option(from Miscellaneous -> Preferences) is changed from tabs into frame. For the "tabs" setting, the pop-up window is opened normal but after changed into "frame" setting its not opened. I've modified layout options for both settings and formdata section codes. But still getting the same issue.
We need your suggestion and modified codes to resolve this issue.
In frame setting,
Here, the calendar edit event pop-up window is not generated by click the section.
Regards
Marimuthu A
