I did do the ElPiedra reshacker fix to correct the graphic bug in the teatimer popup.
As I was doing the change, I remembered that I forgot to make a backup of teatimer before doing the fix.
I just read the Reshacker help manual:
"Modifying (replacing) resources:
Firstly, a warning or two:
If the user intends to modify resources, make sure the original file is backed up first. Then, thoroughly test the 'new' file. To facilitate this, whenever a file is modified and saved, Resource Hacker™ will now automatically make a backup copy of the original file (eg: Explorer_original.exe) before saving the modified file."
