Under the Keyword List, when the count for a given keyword exceeds 99999, the count is displayed with the last 3 digits printed as "...". For example, for a count of 100373, the Keyword List displays it as "100...".
No matter how wide I make the far right panel, keyword counts of 100000 and more will not display the final 3 digits.
I often use the exact counts for inventory control and photo asset management. The loss of the last 3 digits of large counts is a significant burden to these functions.
