Chart Trader w/ IB - bid/ask stop updating

I have 5 workspaces, each has a 1 minute chart going back 2 days with front-month futures.
i chart trading on and it works great.

however, sometimes - mostly with the e-mini S&P - the buttons 'buy ask' 'buy bid' 'sell bid' and 'sell ask' stop updating their prices and if i click on 'buy bid' (after the market has been trading down) and i think i've joined the bid, i get filled right away - (my own fault for not recognizing that it stopped updating)

my question is - is this a known problem? is there a workaround? are there any steps i can take to find out what may be causing this?

oddly, when this happens, it doesn't always affect all of the contracts, only some, and usually only one. i'm wondering if there is some sort of 'throttling' that may be in effect and when there is a burst in e-mini data, something 'breaks'.

any advice would be appreciated.

Hello ecarlino,

That is a known issue that has been already fixed.
Please update MultiCharts to the latest version (9.1 Release 2) and install the updater from this post.
