Sage 2022 Customer Maintenance Custom Tab List-Box

Hi,

I experiencing errors in customer maintenance on a custom tab. I'm using the debug window and found 1k+ lines on several clicks. 

Error:0 Error:11 Error:12 Error:13 Error:14 Error:2 Error:20 Error:23 Error:26 Error:27 Error:36 Error:65 Error:88 Error:95

all lines specify a pvc@---- errno =2 OR xeq@dsp@winapi@ etc.

Any information would be helpful.

Regards
