Best practices for upgrading to 126.96.36.199
When upgrading to 188.8.131.52, we recommend that you re-set all Options. Do this by opening the Options dialog and pressing the Reset button, and Reset All.
We also recommend that you check that your graphics card driver is up to date with the latest driver. You can see this information in Device Manager-->Display Adapters-->Properties-->Driver.
The driver versions should only be a month or two old if its the latest. If you see a date that is older than 2 months, then you should go get the latest driver from the graphics card website (Nvidia, for example).
