Vex coding studio locking up when trying to look at text in modkit after writing block code

Vex Coding Studio is locking up after I switch to the text window to look at code in MODKIT. This is happening on the computers my students use at school and the one I use at home. Computers are PCs and running Windows 10. We have had to delete the program and reinstall it to fix errors such as missing math.h file, etc., but it doesn’t fix the locking up problem. We end up having to use the task manager to close the window.

Additionally, the brains often aren’t recognized by Coding Studio., even though the computer indicates that they have been connected.
