Modal dialog in Premiere Pro (using AE SDK)

Hello all,

I have a plugin that does some long, intensive processing inside a single render call. I show my own progress bar in a modal dialog while this happens.

This is working fine in After Effects, but it's causing a crash in Premiere Pro. I get a few messages through the WndProc but then they just stop coming. I've attached some code below. Does anyone have any idea what might be going on there?

many thanks for any help,

Hugh

Here's the code that creates the dialog:

//assume host window is foregrounded

hostWindow = GetForegroundWindow();

// also tried HWND hwnd; PF_GET_PLATFORM_DATA(PF_PlatData_MAIN_WND, &hwnd);

hDlg = CreateDialog(theDLL, MAKEINTRESOURCE(IDD_PROGRESS), hostWindow, reinterpret_cast<DLGPROC>(DlgProc));

SetWindowLongPtr(hDlg, GWLP_USERDATA, (LONG_PTR)this);

CenterDialog();

ShowWindow(hDlg, SW_SHOW); UpdateWindow(hDlg);

SetForegroundWindow(hDlg); BringWindowToTop(hDlg);

hProgress = GetDlgItem(hDlg, IDC_PROGRESS1);

SendMessage(hProgress, PBM_SETRANGE, 0, MAKELPARAM(0, total));
