Gett black screen when hovering over a variable while debugging

Background:

I run matlab R2014b on a dell precisionM4600 with windows 7 64 bit installed, 16 GB ram using 2 external 24inch monitors.

Every time I hover over a variable in debug mode, my entire 2 screens turn black for a second.

Sometimes matlab will then hang/crash with only the outlines of the matlab windows visible.

I also run R2013b on the same machine (older Simulink application), It never happens with that version.

This is a serious detriment to debugging scripts! What are you guys doing with your tooltips?

If it occurs when you hover over a variable whos contents extend beyond the length of the screen then yes, this is a bug in Matlab's Java interaction.

I was given the following solution by Mathworks support which may work for you if it is the same problem:

• Run MATLAB as administrator
• Execute " edit datatipinfo "
• In line 45 " val = val(1:500); " , reduce number 500 to the length you want (e.g. 10)

I seem to remember 'line 45' was not quite correct, but it is close enough for you to locate the relevant line with common sense.

I think it is working so far...thanks for the quick response. regards Jim
