REF: Win7-64 /PS CS6 /Google-NIK Collection.
After working properly for "a time", I select the Brush option in a NIK plugin, & when the image "re-opens" in PS, the plugin has selected the PS Brush tool, & I can paint on the effect that I'd created, but the Selective Tool Interface fails to open, & there's no way to Apply or Discard the effect.
At that point PS is "hung", waiting for a Command to either Apply, or Discard the Brush effect, but it can't be done without the Selective tool Interface; and the only way out, is CTRL/ALT/DEL to close Photoshop-- & lose your work! (Results in a PS appscrash result).
The Selective Tool Folder contained the SelectivePalette.8Li file, along with a SelToolInst.cfg (Instructional Script for the tool??), and a HDREfexPro2.jsx file.
NIK told me that the HDREfexPro2.jsx file did not belong there, & to delete it, and sent me a SelToolInst.cfg file to replace the existing one; and that fixed the problem for a short time!
Now it works for awhile, then fails.---Wont open either with Brush Command, or from Automate.
I check the folder, & "something" has placed/re-placed the previously deleted HDREfexPro2.jsx back in???
As before, I delete the HDREfexPro2.jsx file, delete & replace the SelToolInst.cfg file with a copy of the very same file that was deleted, and "everything" works properly until after a short while it fails again, & I repeat the same routine again & again!
Since replacing the .cfg file, with a copy of "itself" fixes the problem for a short time; something must be corrupting the file; and what keeps putting the deleted HDREfexPro2 file back (That NIK claims doesn't belong there), is beyond me, & apparently beyond NIK's Customer Service , as well!
