    <p><strong>Screen Shot</strong></p> <p><img src="https://i.stack.imgur.com/qeWWq.jpg" alt="enter image description here"></p> <p>The following source code was used to produce the error above. All you have to do is compile the program and make sure the IDE is still running (the error does NOT happen if the IDE is closed), click the button 12 to 15 times and the error will popup.</p> <p>Once the error has occurred, switch back to the IDE, all the toolbars for the IDE have then disappeared. You have to shut down the IDE and run again, for them to reappear.</p> <p><strong>Source Code</strong></p> <pre><code>unit MainUnit; interface uses Winapi.Windows, Winapi.Messages, Winapi.ShlObj, System.SysUtils, System.Variants, System.Classes, System.StrUtils, Vcl.Graphics, Vcl.Controls, Vcl.Forms, Vcl.StdCtrls; type TMainFrm = class(TForm) Button1: TButton; procedure FormCreate(Sender: TObject); procedure Button1Click(Sender: TObject); private { Private declarations } public { Public declarations } end; var MainFrm: TMainFrm; hDesktop: HWND; implementation {$R *.dfm} function GetHandle(theHandle: HWND; NotUsed: NativeInt): LongBool; stdcall; begin if (theHandle &lt;&gt; 0) then begin hDesktop := FindWindowEx(FindWindowEx(theHandle, 0, 'SHELLDLL_DefView', nil), 0, 'SysListView32', nil); end; Result := (hDesktop = 0); end; procedure TMainFrm.FormCreate(Sender: TObject); var lpss: TShellState; begin ZeroMemory(@lpss, SizeOf(lpss)); try SHGetSetSettings(lpss, SSF_HIDEICONS, False); finally Button1.Caption := IfThen(lpss.fHideIcons, 'Show Icons', 'Hide Icons'); end; EnumWindows(@GetHandle, 0); Button1.Enabled := (hDesktop &lt;&gt; 0); end; procedure TMainFrm.Button1Click(Sender: TObject); const nCmdShow: array [Boolean] of NativeInt = (SW_HIDE, SW_SHOW); var lpss: TShellState; begin ZeroMemory(@lpss, SizeOf(lpss)); try SHGetSetSettings(lpss, SSF_HIDEICONS, False); ShowWindow(hDesktop, nCmdShow[lpss.fHideIcons]); lpss.fHideIcons := (not BOOL(lpss.fHideIcons)); Button1.Caption := IfThen(lpss.fHideIcons, 'Show Icons', 'Hide Icons'); finally SHGetSetSettings(lpss, SSF_HIDEICONS, True); end; end; end. </code></pre> <p><strong>Application Screen Shot</strong></p> <p><img src="https://i.stack.imgur.com/aGWPr.jpg" alt="enter image description here"></p> <p>Any help would be greatly appreciated.</p> <p><strong>UPDATE</strong></p> <p>The IDE toolbars no longer disappear, and the error doesn't appear anymore, thanks to TOndrej for the information about turning off the "Profiler toolbar". Now I get a very annoying flicker that sometimes takes 10 to 15 seconds to return back to normal.</p>

    1. COI suggest you try the Delphi XE, if you can, it looks more stable.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
