# "Open in Web App" Display Frozen

The **bimCAT plugin** uses [Microsoft Edge WebView2 Runtime](https://developer.microsoft.com/en-us/microsoft-edge/webview2/) to display content within the [Open in Web App](https://docs.bimcat.org/user-manual/usage/tallycat-beta/open-in-ec3) window. Occasionally, the window may not properly render the bimCAT Building Planner, leading to issues like prolonged loading, blank displays, or freezes.

#### **Try Simple Solutions**:

* Close and reopen the [Open in Web App](https://docs.bimcat.org/user-manual/usage/tallycat-beta/open-in-ec3) window.
* Restart Revit.

#### **Repair WebView2**:

If the above steps don't resolve the issue, it may be related to the [Microsoft Edge WebView2 Runtime](https://developer.microsoft.com/en-us/microsoft-edge/webview2/) installation. Consider repairing it:

* Exit Revit.
* Navigate to **Windows Start Menu > Add or Remove Programs**.
