Keyboard not showing up after using 'physical' input

[piessequadro]

Installed tabtip on a thin client with touch screen, with license key.

Keyboard is showed up correctly until a key is pressed using a physical keyboard. To 're-enable' correct behavior, I open tab-tip settings from tray icon and modify twice any setting (ie 'scroll into view').

Normally a physical keyboard is not attached but same problem appears using a barcode reader with keyboard emulation: scanning a barcode seems to act exactly as pressing keys on physical keyboard.

Any suggestion to solve this issue?

Thank you.

Indeed a scanner fills up the keyboard buffer as a physical keyboard does.
Windows closes itself the input panel on tap on the keyboard (or scanner). I'm afraid that there is nothing we can do to prevent that.

Touch-It Virtual Keyboard would be an alternative for your needs as it has an option whether to close or not.

Meanwhile I tried Touch It Virtual Keyboard and I confirm the problem does NOT appear.
Thank you.
