Users having problems with adjust page layout

I have a couple of users that are experiencing an odd phenomon when moving visualizations to change the layout on a page.  For example, the user has 4 visualizations on a page in a 2x2 layout.   When she tries to adjust the size of one of the visualization, she is unable to modify the width, instead a vertical black bar appears on the screen and moves with the cursor.   We found that the only way to fix this issue was to: 

1) Go to the control panel and Select Display

2) Set the display to the option "smaller - 100%".   The users had it set at the default, which is "medium - 125%".


As anyone else come across this odd bug?
