Problem with new Version Rated 4 out of 5 stars

I always use your SigSwitch, it's a useful Tool. But with the new Version of TB (24.0.1) and SigSwitch (1.6.12) my Signature is no more visible, totally white instead of the "light grey" as in FAQ explained. With former Version (1.6.11) and TB Vers. 17.0.8 it was still visible. So I deinstalled both TB and SigSwitch new Versions, and re-installed older TB 17.0.8 and SigSwitch 1.6.11 again yesterday. And I am back to normal - Sig again visible. There must be something wrong in compatibility with the newest Versions TB and SigSwitch. I appreciate it when the problem could be solved. Until then I stay with the older Versions of TB and SigSwitch, since it works good. Thank you.
