Filters Not Working in Windows 7 or 8

Hello.

Anyone know why this is? Works good on other versions of windows.

Not sure what version of DHTMLX I have, but I bought it with a heap of development work from DHTMLX about 2 years ago.

Thanks.

Jamie.

Please, try to update the version of your dhtmlx.
You may download a free version and check if it works well in your situation.
