can't change fillament size in easyprint

[freds]

I get an error if I change fillament size in easyprint.
If I start up program size is at 3mm, if I want to change it to 1.75mm there's comming a red "!" with a message "not an integer" And switch it back to 3mm.

if I put it to 1.75 program will not go further and "hangs"...

Did re-instal, tried it on 3 different pc's all the same.

Is there a solution for this ? .I'm unable to print...

[bang]

Here is the latest version,just give it a shot:
