Unstable Entry Form on Surface 4 Win 10 pro

[Tompaps1]

Over the past four months I have been experiencing issues of stability when entering data for time or invoices on my Surface 4 Pro Windows 10 Pro machine.  I have tapping turned off, however, when I am entering data the form cancels and I need to start over sometimes 4 or 5 times.  It takes forever to complete a one time entry.  It may be while I am typing or when I scroll or try setting a date.

It makes the efficiency of the App drop dramatically.  Been using Time Master for almost 4 years now and really need to get this straightened out.

Thanks!
