Maybe somebody from fox team can comment on this.

However, mouse cursor is placed initially to different place without user interaction. This looks VERY stange to users. I need that only user may change mouse cursor placement, not dialog.

One more bug. Add highlighted line to the dialoghandler method.

	_FFC_MEMCPY2(@lcUserCustomFilter, lpUserCustomFilter, nMaxCustomFilter)
	<b>lcUserCustomFilter = Substr(lcUserCustomFilter, AT(CHR(0), lcUserCustomFilter) + 1)</b>
	THIS.cCustomFilter= LEFT(lcUserCustomFilter, AT(CHR(0), lcUserCustomFilter) - 1)

>4. Dialog displays always last filter set by .AddFilter(). Is it possible

Try to change nFilterIndex Property.

>5. If file exists, overwrite promp does not occur. There is

Add property lOverwritePrompt to the class and following code to the dialoghandler method

IF THIS.lOverwritePrompt AND THIS.lSaveDialog
	nFlags = nFlags + OFN_OVERWRITEPROMPT
