Unable to open encrypted pages with 11.0.02 on Win7 IE10 system fully updated.

Just get blank screen with "X" in upper left. Have searched this forum and tried all suggestions including:

1. Cleared and reset all IE10 settings - no luck
2. Disabled and enabled Adobe add-ins - no luck
3. Right click on link and 'save as' or 'open' and others on the Tool menu - no luck
4. System restore - no luck
5. Disabled and enabled other add-ins - no luck
6. My win8 IE10 system opens encrypted pages with no problem. I set the IE10 tab options identically in the win7 system - no luck
7. Contacted websites using encryption (bank and credit cards). They have no other suggestions.

Any other suggestions?
