Was curious as to the cause, my app does it, as well as the base project. Here's how I tested:
1. Place a basiclabel on the form and point to a string, I used CLX.
2. Set to use alpha keyboard.
3. During runtime if I type a value and click the enter key it's normal.
4. During runtime if I hit enter on my keyboard, the UI freezes for about a second.
5. The UI doesn't freeze if I type other keys on my keyboard.
How can we prevent this?
Edit: I forgot to mention the way I noticed lag/freezing is place a gif on the form, like the one attached. I usually do this during development as a gauge for how things are going.
