Cannot find TTerminal VCL component

Q: I installed the TTerminal component, but when I open the Manager project, the TTerminal is lost and Delphi says that it can't find the TTerminal component? But it is on the Delphi IDE when I start Delphi.

A: Probably MandySoft_VCL.bpl is hidden package for project. Look "Project options/Packages" and check appropriate check box. If it does not help try to find "MandySoft_VCL" text in registry (regedit.exe). Delphi is able to hide package generally.

Happen in D7, too

You are right it happen to me too in D7 (not in D5). The problem is in a bug in IDE when IDE reads resources and dislikes something in resource used in Kylix. The result is TTerminal silently disappears from palette.

{$IFDEF LINUX}
{$R *.xfm}
{$ELSE}
{$R *.dfm}
{$ENDIF}

The workaround: make negation:

{$IFNDEF LINUX}
{$R *.dfm}
{$ELSE}
{$R *.xfm}
{$ENDIF}
