i don't have Windows 98 anymore. you should be able to delete faxes from the queue by selecting one and deleting it. since you use different programs, either one of them could be retrying. you will have to start the FAX programs and see if there is anything queued in their To Do list and to see in the options if you can disable retrying of unsent faxes.

I tried sending a fax
I heard it dialing, but would not connect with the other fax machine.
One error message said 'Undeliverable' 'No Carrier'
I thought maybe the fax machine was unavailable after business hours so I sent the fax to transmitt the next morning at 9:20 am. I don't think it went because it is still in the outbox, and not in the sent folder. Everytime I open Windows Messaging it puts another fax in que, There are six now and I can not cancel them, It won't allow me too. What's the fix?
Windows98 OS
Tried faxing with Microsoft Fax and Impact ColorFax Lite
