Form jumps to the right/left

Good day,

I have a 16 page form with about 8 tables, tables have 12 columns each.

When testing and previewing my form, I complete the first row of the table,

but when I scroll to the left to start completing the second row, my form/scroll bar just jumps to the far right.

Can you please assist me I have a demo in an hour.

I thought its the code in layout:ready event but I have removed it, but that only helped the performance of the form

Regards,

Ace
