Hi, billo255, and welcome to the DonationCoder site. Apologies for the late reply.
Are you running XP as well?
Are you running the beta version, by chance? If not, I made some improvements in the beta that, hopefully, solve the issue:

As the post says...back up your data first if you want to try it. However, if you do, please let me know if the issue still appears.
I'll add this to my ToDo but I wouldn't hold my breath for this one.
Colouring the series shouldn't be difficult but I'm not sure how I would determing an on-the-bubble show. I can only go off the status data in the data files.
At any rate, it'll be several weeks, at least, before I can get back to coding much. My regular day job is keeping me quite busy at the moment.
Thank you for the kind words. It's been a fun application to write and I'm glad you find it useful.
Just to add another voice to the list regarding "artifacts" I've go them as well.

A major issue that seems to be intermittent on my version of epCheck (and what prompted me to join this forum today) is the loss of checkmarks after doing a refresh.

-Wish List -
1. Display unwatched back episodes.
I'll add this to my ToDo but I wouldn't hold my breath for this one.
2. Cancelled, Ended, Continuing, Summar - When a show is pulled off the air and I've watched all of the episodes I delete the series from epCheck. Rather than having to scroll through all of the series to see if the status has changed, a tab showing a list of all of the series and the status might be be a useful feature to catch shows that were reportedly being ended but then revived (i.e. Unforgettable and Perception). It might not be 100% effective but would save having to scroll through all of the series after a refresh to see if anything has changed. (Also, maybe the series name could be color coded to identify its status? red=ended/ending, green=continuing, orange=on the bubble?)

Nice job on creating a useful tool for us TV'o'phile's who only want to track our favorite shows.

(sincerely, and no sarcasm intended). I'm currently in between "opportunities"... 
BTW, which version of epCheck are you using?
