Creo 10 Model Tree: Too large width of "Windchill Server Status". Value cannot be changed.

My colleague and I got a new laptop.

We are using Creo 10.0.4.0, connected to Windchill.

With this new install the column “Windchill Server Status” is very wide, and much wider than 8, which it should be according to the "Model Tree Columns” settings.

Also, the value of 8 cannot be changed, it is greyed out. The other widths can be changed without issues.

What is wrong? What should we change to bring the column width of "Windchill Server Status” back to 8?
