Hi,

I've tested the ToolBoxBrowser demo using the showmodal function for the child forms and I couldn't reproduce your error. I could open and close the child form many times and it always loaded google.com successfully.

If you are trying to open local files it's recommended to use a custom resource handler for security reasons.
Open the CustomResourceBrowser demo and use that code as the base for your child form.

I've used the Indy components in BriskBard to send pings without problems. Use them if you have problems with those functions.
