Typing in tables abnormally slow

I had bought DEVONnote and started to use it now. I made a table, but when typing into it, the text types very slowly, and using the backspace (delete) key erases the text abnormally slow. I am referring to about 10 seconds to delete 5 characters. Have you ever experienced this, and found what the problem is?

The problem is simply that you have run out of free physical RAM and are operating using Apple’s Virtual Memory, which is disk-intensive and is often slow.

Closing other applications and quitting and restarting DT Pro should free up memory in RAM and speed everything up.

Hence the old saying: “RAM is good. More RAM is better.”
