Budgets - Tab Key Not Functioning

Is it just me or has the Tab key to move to the next cell on the right, and shift tab to move to the previous cell on the left, stop working.

 

I have tried on a few different PC's and it seems to be fairly consistent.

 

This has made entering or edit Budgets considerably more difficult.

 

I cannot imagine this would be intentional because that would be crazy.

 

Another bug that MYOB needs to get fixed in a timely manner, which does not mean 2 years (which MYOB took to rectify a tabbing issue in AccountRight that was reported in General Journals a few years ago).
