The Text Cursor Indicator is a Windows feature that Mosaic doesn't support or test with.
One of our developers identified a known issue when using the Text Cursor Indicator alongside Excel. If you're running Excel at the same time, a memory leak may slow down your computer, which can affect your browser performance and Mosaic responsiveness.
You might see this in the Windows Task Manager under system resource usage.
If you're experiencing slowness while using both Excel and Mosaic, we recommend turning off the Text Cursor Indicator as a possible workaround.
