Hello Mirek,

Commenting SysImageRealized doesn't help. Also, commenting w.DrawImage(), too. What helped is commenting loop with angle:

		//for(int angle = 0; angle < 360; angle += 30)
		//	w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle " + AsString(angle));

So, following code works fine on 32-bit windows:

	virtual void GLPaint() {
		Size sz = GetSize();
	
		GLDraw w;
		
		w.Init(sz);

		w.DrawRect(0, 0, sz.cx, sz.cy, SWhite);
		w.DrawRect(10, 10, 30, 30, SRed);
		w.DrawLine(45, 45, 80, 120, 4, Blue);
		w.DrawLine(80, 90, 400, 0, PEN_DASHDOT);
		
		w.DrawImage(200, 10, CtrlImg::reporticon());
		w.DrawImage(280, 10, CtrlImg::reporticon(), Red());
		
		const char *text = "This text is centered";
		Size tsz = GetTextSize(text, Arial(25).Bold());
		
		w.DrawText((sz.cx - tsz.cx) / 2, (sz.cy - tsz.cy) / 2, text, Arial(27).Bold(), SBlue);
		w.Clipoff(200, 50, 95, 100);
		w.DrawText(0, 80, "CLIPPED", Roman(25));
		
		//for(int angle = 0; angle < 360; angle += 30)
		//	w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle " + AsString(angle));
		
		w.End();
	}

------------------
OK, after digging more AsString(angle) is causing crash. It works good with following line of code:

w.DrawText(sz.cx - sz.cx / 3, sz.cy - sz.cy / 3, angle * 10, "x   Text with angle " /*+ AsString(angle)*/);

Replacing AsString with IntStr cause the same error. I think the problem must be with utoa32 (Format.cpp) function and it's memory management on 32 bit architecture.
