My web viewer looks like this

"http://myserver.com:8020/SuperContainer/Files/Insights/" & Contacts::_id&"?style=noscroll+nodelete"

But a few issues

Scroll bar still shows

No delete works but right clicking anywhere in the viewer does not bring up the dialog.

Seems the target area is only to the right corner.

Once the contextual dialog comes up there is no way to dismiss it with using the escape key.

Client is FMP 11 Advanced V2.

I'm not able to reproduce this issue. Keep in mind that in filemaker you may need to left click into your web viewer (and the java applet in this case) in order to give focus to the java applet.

What are you storing in the web viewer? What size is your web viewer? Your images should be automatically resized to fit in the web viewer. Files which cannot be previewed should show a file icon and a description. The noscroll style will stop the scroll bars from showing up if you web viewer is so small that the file description extends past the size of the web viewer. Is this not happening for you?
