Сan not enter the value of modifiers.

[vbl2007]

When setting the Transparency modifiers, I cannot manually (from the keyboard) set negative values. Arrows (up and down) don't work either. Only built-in parameters (-1000, 0, 1000), or moving the mouse left-right, changing the parameters. Copying from the clipboard doesn't work either. The values -1000 and 1000 change the parameter abruptly, while the values -100 and 100 smoothly. I wanted to try other negative/positive values.
P.S. Yesterday I could not enter negative values, today too. Restarting the computer, loading the project - the same result. Cleared memory by 2% (memory load from 43% to 41%) - everything works fine, negative values are entered, arrows work. PTE latest version. Mystic...
