This is suppose to happen with Space bar : Splitting - By hitting the space bar the player can split their cell into two smaller cells, both half of the original cells mass. One cell will remain where the splitting cell was, and the other will project forward in the direction of the cursor.

While you are on that site, could you double-check this setting:

Call up the Permissions panel of the Page Info dialog using any of these:

• right-click a blank area of the page and choose View Page Info > Permissions
• (menu bar) Tools menu > Page Info > Permissions
• click the padlock or "i" icon to the left of the site address, then the ">" icon, then More Information > Permissions

Check the permission for "Override Keyboard Shortcuts". Usually the "Use default" box is checked and there is a gray bullet next to Allow. If yours has a bullet next to Block, click Allow (if necessary, uncheck "Use default" to enable the Allow selection).

If you changed that, does it make any difference?
