Remove Mouseover color in Titles

[bioCam]

Hi, i have a List report with Section groupings and columns titles.  Column titles are multi-row with mutil-columns span together.  Titles background is deep blue color and I have adjusted the borders to make a mulit-row column looks like a single column (since I cannot merge multi-row). 

In Cognos Viewer, when mouseover any titles and Section title, it turns the deep blue background color into the default lighter blue.  Above the titles are hard-coded hyperlinks.  Users would be moving the mouse crossing the titles to the hyperlinks and it would be most annoying to see the flickering colors from deep to light to dep blue.

Is it possible to remove the mouseover event action.  If not, can I set the color to be consistent with my deep blue background color?  Please help - i ahve been googling for a while and found no solution.

Thank you.
