Thanks you all for your suggestions and kind comments. Re-sizing Netscape Navigator in quick succession can occasionally cause BrowserMaster to crash. Both browsers don't consistently pop to the front of the desktop on resize attempt. BrowserMaster does not attach to an open Internet Explorer window on resize attempt. Netscape Navigator's position can get 'confused' when attempting a resize while two windows are open to the same web page or with the same title.
Suggestions are welcome.
On Some windows machines, the title bar is a gradient which can use up a large percentage of available colors. Fixed requesting to size Netscape twice if not currently running. Now BrowserSizer waits till Netscape is loaded, then attempts to re-size. The BrowserSizer name seemed out of date with all of the enhancements in version 2.0. The setups it created were too bloated.
